AIMS The purpose of this paper was to present the results of a simple modification of the suture technique for pulmonary artery banding (PAB), which allows for stepwise debanding by use of balloon catheter. METHODS AND RESULTS During the period 1985-2007, PAB operations were performed in 227 children at Rikshospitalet. Of these children, 14.5% (n = 33) were treated by balloon dilatation of th...

The aim of this study was to clarify how collagen deposition or medial hypertrophy of the vascular wall affects the coronary dilator reserve in pressure-overloaded hearts and whether inhibition of collagen deposition reverses the abnormalities after relief of pressure overload. We used ascending aortic banding and debanding methods and superimposed beta-aminopropionitrile in some of the banded ...

Backgrounds: Bilateral pulmonary artery banding (bPAB) followed by ductal stenting has been reported as a stage 1 palliation of hypoplastic left heart syndrome (HLHS). However, hybrid strategy, which includes median sternotomy for bPAB, has been a common approach. In this preliminary experiment, we investigated the feasibility of a transcatheter bPAB followed by debanding using a reexpandable c...

BACKGROUND Aortic banding and debanding models have provided useful information on the development and regression of left ventricular hypertrophy (LVH). In this animal study, we aimed to evaluate left ventricular (LV) deformation related to the development and regression of LVH. METHODS Minimally invasive ascending aorta banding was performed in rats (10 Sprague Dawley rats, 7 weeks). Ten rat...

A variety of luting cements are available for use with orthodontic bands. This in vitro study was conducted to evaluate the force required to cause debanding when zinc phosphate, polycarboxylate and glass ionomer cements are used as the luting agents; and to determine whether sandblasting the inner surface of orthodontic bands affects the force required to deband. The data were obtained by deba...

statement of problem: fixed orthodontic appliances can interfere with removing bacterial plaques from dental surfaces which can ultimately lead to white spot formation. purpose: the aim of this study was to evaluate the quantity of white spots and areas of decalcification following fixed orthodontic treatment. materials and methods: a total of 100 patients undergoing or scheduled for fixed orth...

Esophageal perforation is a serious complication that requires prompt recognition and treatment. We present the case of a patient with lower esophageal perforation that apparently resulted from orogastric calibration-tube passage during laparoscopic placement of a gastric band. The complication was diagnosed early postoperatively, and was able to be successfully treated by laparoscopy,debanding...
